Specicaton of Lettersy Patent.

Patented Dec. 25, 1906.

To all whom t may concerng' y Be it known that I, SWAN F. SwANsoN, a

citizen of the United States, residing at Pueblo, in the county ofPueblo andState of Colorado, have invented certain new and useful Imrovements in Dumping-Cars; and I do decljare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in theart to which it appertains to make and use thesame.` A

,My invention relates to improvements in dumping-cars, wagons, and thelike g and it consists in thel construction, combination,v

and arrangement of scribed and claimed.

The object of the invention is to improve parts hereinafter dej andsimplify the construction and operation of devices of this character,and thereby render the` same more durable and eiiicient and lessexpensive. v

The above and other objects are accomplished by the constructionillustrated'in the accompanying drawings, in whichvFigure l is a 4bottomplan view of the body of a dumping-car constructed in accordance with'my invention. Fig. 2 is avertical longitudinal sectional view taken onthe plane indicated by the line 2 2 in Fig. 1. Fig. 3 is a verticaltransverse sectional view through the same, taken on the plane indicatedby the vline 3 3 in Fig. 1; and Fig. 4 is a detail sectional view takenon th plane indicated -by the line 4 4in Fig. 1. i I

i The present embodiment of my invention is in the form of a rectangularcar or wagon body 1,v constructed of metal and having straightorvertical sides 2 and ends 3; but it will be understood that theimprovements may be appliedto a car, wagon, lor the like of anyvform andconstruction which may have either straight or inclined ends and sidesand any number of swinging bottom-sections.v

Four`bottom-sections 4 are shown inthe drawings, and these are arrangedin pairs and` hinged at 5 to the inner faces of the sides 2 a shortdistance above the lower edges of the latter, 'so that they will swingdownwardly and outwardly from the center of the car. The lower portionsofthe sides and ends 2 3 of the body are strengthened by angle-metalbars 6 and flat bars or plates 7, and upon the inner or Jfreelongitudinal edge of two of the bottom-sections 4 are providedprojecting ledges or tongues 8 to effect a tight joint between themeeting ends of the opposingbottom-sections, asshown in Fig. Between theside edgesof the adjacent bottom-sections and at the ends of the bodyare transverse sills 9 in the form of I-beams, which have secured upontheir tops plates 10, the. projecting edges of the latter being adaptedto limit the upward swinging movement of the bottom-sections 4. l

The bottom-sections 4 are swung open and closed by rotating a lever,crank-handle, or

Athe like 11 upon one end of a longitudinal shaft 1,2, journaled insuitable bearings upon the outer face of one of the sides 2 of thecarbody. A pawl-and-ratchet locking device 13 is provided at said end ofthe shaft to hold the latter' against rotation, and hence thebottom-sections 4 in their closed position. Upon the shaft 12 aresecured pinions 14, which project through slots in the side 2 and meshwith gears 15, secured on short shafts 16, extending through the I-beams9 and the upwardlyextending arms or ends of U-shaped bearingbrackets 17,secured upon the bottom flanges of said I-beams, as shown in Fig. 4.Upon said short shafts 16 on opposite sides of the I- beams are'securedgrooved pulleys or drumsl 18, to which are attached and upon which arewound chains or other flexible connections 1 9. The opposite ends ofthese chains 19 are divided to provide two branches 20 21, which passover guide-pulleys 23 upon the I-beams and have theirends attached tothe eyes of bolts 23. The latter are mounted in the bent lower ends 24of arms or brackets 25, secured lupon the bottom faces of thebottom-sections 4, as clearly shown in the drawings. It will be seenAthat when the shaft 16 is rotated in one direction the chains will beAunwound from the drums 18 and the bottom-sections of the car or wagonwill swing to their lowered or opened position and that when it isrotated in the reverse direction said chains will be wound upon thedrums 18 and the bottomsections will be'swung up to their elevated orclosed position. The pawl-and-ratchet device retains them in the latterposition. Any suitable means may be provided for adjusting the length ofthe branches of the chains.

From the foregoing description, taken lin connection withtheaccompanying drawings, the construction and operation of theinvention will be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the .minor details ofconstruction maybe resorted to without departing from the prinrool I no

`flexible connections between said arms and said windingf drums,substantially as described.

2.' A dumping-car or the like comprising walls, bottom-sections hingedto swing, from said walls, beams connecting said walls, a long shaftupon one of said Walls, short shafts upon said beams, gearing betweensaid long and short shafts, guides upon said beams, dep endingbracket-arms upon said bottom-sections, winding-drums upon said shortshafts, flexible connections between said arms and said winding-drums, alever upon said long shaft, and a paWl-and-ratchet locking devicebetween said long shaft and one of the walls of the car, substantiallyas described.

.ln testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
